SUMMARY: This AD results from mandatory
continuing airworthiness information (MCAI) originated by an
aviation authority of another country to identify and correct an
unsafe condition on an aviation product.

The MCAI describes the unsafe condition as:

It has been determined that
modifications by DECA Aviation Engineering Limited on Bombardier
Inc. DHC-8 Series 200 aeroplanes with their Cargo Conversion and
Abrasion Protection Systems, Supplemental Type Certificates (STCs)
SA97-106, provide inadequate fire protection and decompression
venting means. This can lead to an uncontrolled cargo fire and
structural damage.

This AD requires actions that are
intended to address the unsafe condition described in the
MCAI.
